T on whom it may concern:

Be it known that 1, WILLIAM J. FAHNLEY, a citizen of the United States, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Heel-Nailing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in heel-nailing machines; and it consists of mechanism for perforating the heel to receive the nails before the heel is attached to the boot or shoe sole, and also of mechanism for driving the nails inserted in the heel-perforations in the shoe-sole, and of a device for spanking the top lift onto the heel after it has been secured to the shoe-sole, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure 1 represents a front elevation of the machine. Fig. 2 represents a side elevation of the same as seen from X in Fig. 1. Fig. 3. represents a vertical section of the same. Fig. 4 represents a longitudinal section on the line Y Y, shown in Fig. 3. Fig. 5 representsa detail perspective View of the cam for raising the jack. Fig. '6 represents detail end and side views of the knee-lever for operating the awl-block or heel-perforating device. Fig. '7 represents a detail section of the head of the machine, showing a shoe in position on the jack for spanking the top lift to the heel. Fig. 8 represents a detail front View of the longitudinally-adjustable driver and spanker blocks. Fig. 9 represents a horizontal section on the line Z Z, shown in Fig. 8. Fig. 10 represents a bottom view of the driver and spanker blocks. Fig. 11 represents a crosssection on the line V V, shown in Fig. 10. Fig. 12 represents a cross-section on the line 7 WV, shown in Fig. 10. Fig. 13 represents a cross-section on the line U U, shown in Fig. 10. Fig. 14 represents a detail perspective View of the nail-driving plate. Fig. 15 represents a perspective View of the heel after its perforations have received the nails preparatory to driving the same; and Fig. 16 represents a detail cross-section on the line T T, shown in Fig. 4. Fig. 17 represents a Vertical section of the awl-block and awls.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

a is the frame or standard of the machine, in bearings in the lower portion of which is journaled the drivingshaft I), having attached to it outside of the standard a the balance-wheel b and fast pulley Z). b is a loose pulley on the rear end of said shaft 1) for the purpose of shipping on it the drivingbelt when the machine is not in use.

The shaft Z) is set in a continuous rotary motion by means of belt-power applied to its pulley b", as is usual in machinery of this kind.

The mechanism for perforating the heel for the purpose of loading it with the nails by which it is to be attached to the boot or shoe 7o sole is constructed as follows: On the driving-shaft b is attached the eccentric-block c, surrounded by the strap (1', having made in one piece with it or secured to it the up wardly-projecting rod d, as shown in Figs. 2, 3, and 4. The upper end of the rod d is jointed, by means of a pin 61', to another rod or link e, the upper end of which is jointed at e to the lower end of the vertically-movable plunger-rodf, adapted to move up and down in a suitable bearing in the standard a, as shown. To the upper end of the plunger fis secured the awl-block carrier f preferably provided with a downwardly-proj ecting screwthreaded spindle f working in a correspond- 8'5 ing screw-threaded vertical bore in the upper end of the plunger f, as shown in Figs. 3 and 4. The carrier f is preferably made dovetailed for the reception of the correspondingly-shaped awl-block g, which is horizon- 9o tally adjustable therein, and may be secured to it by means of set-screws or equivalent devices.

g g are the awls secured to the awl-block g.

h is a heel-rest plate, secured in a suitable manner to the standard a, and it is perforated to receive and allow the awls g g to pass up through it during the operation of perforating the heels.

The perforated heel-rest h is preferably supported and located in grooves a a in the standard a, so that it may be removed therefrom and substituted by another, according to size of the heel to be perforated and the number of awls used on the awl-block. Above the perforated heel-rest his secured to the standard a the block 1', to the under side of which is adjustably secured the upper heelrest plate 11. To the side of the standard a is pivoted at'k the knee-lever 7a, to the forward end of which is connected the rod 7c", the lower end of which is connected to the treadle-lever 7o, pivoted at 70" to the floor or lower part of the standard a, as may be most suitable. The treadle-lever it the rod la, and knee-lever 7e are normally held in the positions shown in Fig. 4 by the influence of a suitable spring 70 when the perforating device is not in operation.

During the rotation of the shaft 1) no vertical motion is imparted to the plunger f as long as the treadle k is not depressed, owing to the fact that the rod (Z is loosely jointed to the link 6 and the latter to the plunger f, and to impart a vertical motion to said plunger f it is essential that the rods (Z and 6 should be held temporarily in a line with the said plunger, and for this purpose I make use of the following mechanism: To the upper end of the knee-lever 7c is loosely pivoted at the dog 70 which is prevented from swinging toward the left, Fig. 4:, by its lower end coming in contact with a pin or side projection 7.2 on the knee-lever 7:, as shown in Figs. a and 6. On the side of the rod (Z is apin or projection (Z against which the upper end of the dog k comes in contact when the treadle 70 is depressed, causing the rod (Z and link 6 to be moved in a line with the plunger f, and as the rod (Z is forced upward while in such a position the projecting end of its hinge-pin (Z is caused to enter a vertical groove Z in a stationary guide I, secured to the standard a, as shown in Figs. 4 and 16, by which the rod (Z and link e are held in a linear position relative to the plunger f by the depression of the treadle 70", and thus causing a vertical move ment to be imparted to the plunger f, awlblock carrier f, awl-block g, and awls g g. By removing the downward pressure on the treadle 70 it and the knee-lever 7e are automatically returned to their normal positions, (shown in Fig. 4,) allowing the driving-shaft Z) to rotate without imparting a vertical motion to the plunger f.

To perforate the heel it is only necessary to place it in position between the heel-rests h and e" and to depress the treadle 7,1 when an upward movement is imparted to the awlblock and its awls, as above described, causing the latter to penetrate the heel and drop down to the positions shown in Figs. 3 and 4:, when the perforated heel is removed and another one put in its place to be perforated, and so on. The heel so perforated is loaded by hand with nails, as is common in machinery of this kind, and subjected to the driving and spanking operation in the machine.

The mechanism for driving the nails and spanking the top lift on the heel is constructed and operated as follows: A is the forwardlyprojecting head on the standard a, and to the under side of the same is secured in a suitable manner the plate A, on Which is longitudinally adjustable the driver and spanker block carrier m, the latter having, preferably, for this purpose a dovetailed longitudinal recess adapted to fit a corresponding dovetailed rib or projection on the under side of the plate A, as shown in Figs. 1, 3, 7, and 9, by which arrangement the carrier m can be moved to the right and left 011 the plate A for the purpose of moving the driver-block and spanker-bloek alternately to positions centrally above the shoe-holding jack, as will hereinafter be described. The driver-block consists of a plate 77., having, preferably, a dovetailed projection n on its upper side adapted to fit a correspondingly-shaped recess in the under side of the carrier m, by which arrangement the said plate or can be adjusted forward or back on the carrier on for the purpose of securing the driver-block in a proper position to said carrier relative to the heel that is to be nailed. Below the plate a is arranged the vertically-yielding plate N, which is prevented from getting detached from said plate a by means of headed bolts n a", passing loosely through vertical perforations in the yielding plate N and screwed into the plate '22 as shown in Figs. 8 and 11. The plate N has a heel-shaped or arched slot or perforation N made through it, the contour of which corresponds to the curved line in which the nails are to be driven in the previously perforated and loaded heel, and in said slot is vertically adjustable a correspondingly-shaped nail-driver plate O,having atop piece or cover 0, between the under side of which and top of plate N is located a suitable spring 0" for the purpose of holding the upper end of the driver-plate 0 against the under side of the plate at and holding the plate N expanded from the said plate a, as shown in Figs. 8 and 11. The lower edge of the naildriver plate 0 has a series of notches or reeesses O 0 corresponding in positions to the locations of the nails in the heel, or a portion of such nails, and serves for the purpose of allowing thenail-heads of the nails directly below such notches to project slightly above the top of the heel to permit the top lift to be afterward spanked on the projecting nailheads.

m is a set-screw going through one end of the plate 171 for the purpose of seen ring to it the plate it after the latter has been properly adjusted.

The spanker device consists of a plate 17, having, preferably, an upper dovetailed projection 1), adapted to fit, and to be adjusted forward and back in a corresponding recess in the under side of the plate m, as shown in Figs. 1, 8, and 11, in the same manner and for the same purpose as the plate a, hereinbefore described.

m is a set-screw for the purpose of securin g the plate 1) in position on the plate on after it has been adjusted forward or back relative to the position of thejack below it. Below the plate 19 is arranged the vertically yielding plate P, which is loosely connected to the plate 19 by means of headed screws 19 1) going loosely through vertical perforations in the movable plate P and screwed into the plate 19, as shown in Fig. 11. The plate P is normally expanded from the plate p, as shown in Figs. 1, S, and 11, by means of a spring 13 interposed between the plates p and P.

R in Figs. '7, 1O, 11, and 13 is the top lift that is to be spanked on the projecting nail ends (1 q q of the heel Q, after the latter has been secured to the bootor shoe, and said top lift is temporarily held on the under side of the plate P as follows: On the under side of the plate P, at the forward end of the same, is a rib P, against which the breast of the top lift is made to rest, as shown in Figs. 10 and 13. v

P" is an angular plate, the rear end of which is attached to a pin P passingloosely through a perforation in the plate P and automatically pulled toward the front of the machine by means of a suitable spring P, which causes the front lower portion of the angular plate P to bear against the rear part of the top lift R, as shown in Fig. 10. The forward end of the spring-pressed plate -P is preferably made forked, as shown in Fig. 10, so as to cause the top lift to be automatically centered when pushed into position on the under side of the plate P. To secure a top lift temporarily in position on the under side of the plate P, it is only necessary to push the pin P slightly backward, causing the angular plate P" to be moved back sufficiently to enable the top'lift to be placed on the under side of said plate P between the rib P and forked .end of the plate P. By removing the pressure on the pin P the angular plate P is drawn forward by the agency ofthe spring P causing the top lift to be held between said rib P and forked end of the plate P, as shown in Figs. 10 and 13.

The carrier on has attached to it one end of the flat spring M, having secured to its free end a knob M, having a pin M, passing loosely through a perforation in the side of said carrier m, and having its inner end adapted to be locked in either one of the two locking recesses A A in the side of the plate A, as shown in Figs. 8 and 9. It will thus be seen that when it is desired to bring either the driver-block or spanker-block opposite to the shoe-holding jack all that it is necessary to do is to take hold of the knob M and pull the pin h outward sufficiently to disengage it from the recess A" or A in which it was spanking on it the top lift.

locked, and to slide the carrier m to the right or left, as the case may require, and secure it to the plate A by allowing the pin M to enter the corresponding recess in the plate A. Suitable stops may be arranged on the plate A to limit the sliding motion and adjustment of the carrier m, as is common in machines of this kind.

S is the jack on which the shoe Q is held during the operation of nailing the heel and Said jack is pivoted at S to the upper forward end of the screw-threaded rod S, the lower end of which is guided in a vertical cylindrical recess in the upper end of the vertical plunger S The screw-rod S is splined in said recessed plunger S so as to prevent its turning around its axis; but the rod S" is otherwise free to be raised or lowered therein, which is accomplished by means of a nut S, surrounding the screw S and supported on the upper end of the plunger S as shown in section in Fig. 3. By this arrangement the jack S can be adjusted up or down according to the height of the heel that is to be nailed or spanked. The plunger S is vertically movable in a bearing a in the front portion of the standard a, and it is splined therein, so as to prevent its turning around its axis while moving up and down in said bearing. The lower end of the plunger S is pivoted at S to a lever t, which is normally held in the inoperative position shown in Fig. 1 by the influence of a suitable spring f. The lever 25 has at its lower end a front projection t and a side lip 29, for purposes as will hereinafter be described.

To the pin S is pivoted the upper end of the treadle-rod t the lower end of which is suitably connected to the treadle-lever i pivoted at t to the lower part of the standard a, and connected by means of a spring t to the said standard a, as shown in Figs. 1 and 2, which mechanism serves for the purpose of lowering the jack by depressing the treadlelever 6 to enable the shoe to be placed in position on the jack preparatory to nailing the heel on said shoe, by the forcing upward of the said jack and the loaded heel against the driver-block and afterward against the spanker-block, as the case may be.

The mechanism for forcing upward the jack S and its plunger S is constructed as follows: On the front end of the rotary driving-shaft b is secured a hub B, having a tooth or proj ection B and a face-cam B", for purposes as will be described. The projection B serves to swing the lever 23 to an upright position by actuating the projection t on said lever, and the cam B serves to raise the said lever 15 upward by coming in contact with the said projection 25. It will, however, be observed that when the levert is in the position shown in Fig. 1 the shaft Z) and its cam may rotate without coming in contact with the projection 25", and for the .purpose of causing the projection B to move the lever 25 to an upright position preparatory to causing the'cam B" to raise it, it is necessary that the lever '6 should be swung sufficiently in the direction of the arrow shown in Fig. 1 to permit the projection 13 to engage with the projection t" on said lever 2, and this is accomplished by a treadle-and-pawl mechanism as follows: In a bearing or bracket a secured to the front of the standard a, is guided the rod to, the lower end of which is suitably c011- nected to a treadle-lever u, pivoted at u to the lower portion of the standard a, as shown in Figs. 1 and 2, which treadle-lever and red are normally held upward in the positions shown in said figures by the influence of a suitable spring a one end of which is attached to the standard a and the other end to the treadle-lever 10. Below the bracket a is pivoted to the rod u the pawl M4, to the outer extension of which is connected a spring if, having its other end attached to the rod to below said pawl, as shown in Fig. 1. The operation of said treadle-and-pawl device is as follows: Supposing the levert and the rod u, with its pawl a to be in the positions shown in Fig. 1 and it is desired to swing the lever t in the direction of the arrow shown in said Fig. l sufficiently to bring the projection B in contact with the projection 15 on the lever 1, this is accomplished by the depression of the treadle-lever a and its rod 11, by which the pawl it is caused to act on the lever 13 and its projection 25 so as to swing it in the direction shown by the arrow in Fig. 1 sufficiently to cause the projection 15 to act on the lever projection t, and thereby to swing the said lever 16 to an upright position, when by the further rotation of the shaft 1) the cam B" comes in contact with the said lever projection 25, and thereby forces the lever 25, its plunger S and jack S, with the shoe held thereon, upward against the driver-block, and thus causes the nails in the heel to be driven through the shoe-sole and clinched against the metal jack. After the heel has thus been attached to the sole the jack is moved downward by depressing the treadle-levcr t and the carrier on is moved toward the left and locked in position, so that the spanker device is placed directly above the jack, when the treadle u is again depressed for the purpose of swinging the lever ttoward the left, when it is again forced upward by the action of the cam B on the projection t and the top lift spanked on the top of the heel by the device, as hereinabove mentioned, and so on during the operation of the machine.

In placing the shoe on the jack S or removing it therefrom it is swung forward around its fulcrum, as shown by dotted lines in Fig. 3.

The awls g are preferably provided with outwardly-inclined or tapering points 9" g, as shown in detail in Fig. 17, so as to cause them to penetrate the heel in curved directions from the center of the heel outward, so as to cause the points of the nails to be turned outward and more easily clinched when driven against the metal jack.

Having thus fully described the nature, eonguide for receiving a pin or side projection on the latter, substantially as and for the purpose set forth.

2. In a nailing-machine, a horizontally and longitudinally movablecarrier and a n ail-driving device consisting of an upper plate sooured to the carrier, and a vertically-yielding lower plate having a curved or heel-shaped perforation through it, and a correspondinglyshaped nail-driving plate working in said perforation, substantially as and for the purpose set forth.

3. In a nailing-machine, a movable carrier and a nail-driving device consisting of an upper plate secured to the carrier, and a vertically-yielding lower plate having a curved perforation," as described, and a correspondingly shaped nail driving plate having notches or recesses at its lower end, substantially in a manner and for the purpose set forth. I
